The top number is called the numerator.
atomic number
The top number in an improper fraction is called the numerator. The bottom number is called the denominator.
The number on top of a fraction is called the numerator. It represents the number of parts being considered.
The number on the top of a fraction is called the numerator. The number on the bottom is the denominator.
The top number in each element represents the atomic number of the element, which is the number of protons in the nucleus. It determines the element's chemical properties and its unique identity on the periodic table.
Calcium has 20 Protons. You can determine the amount of Protons in an Element by checking the top number of an element. This is called the Atomic number. Calcium has 20 protons
the number of protons in an element is called the atomic number and there is no way to see how many electrons an element has.
The number of protons in an element is the atomic number, which can be found in the top right corner of the box containing the element.
The hole numbers on the top of each element represent the atomic number. This number indicates the number of protons in the nucleus of an atom of that element. It is a unique identifier for each element on the periodic table.
The top number is called the numerator.
The number at the top of an element square is referred to as an atomic number. This number provides you with multiple information such as the number of protons and electrons the element has, and with the atomic number it is easier to locate the element on the periodic table. In this case, Carbon's atomic number would be 6, as well as how many protons and electrons are in its nucleus.
the answer is that it is called a atomic number.
The number of protons in an atom of an element is equal to the number of electrons in that atom which is equal to that element's atomic number.
The atomic number of the element is the subscript (bottom number) and the mass number is the superscript (top number); and both those numbers are written to the left of the element symbol.
They are called isotopes,
